A new farming method is having a dramatic effect on maize crops in Malawi. And assistance is coming from a solar-powered tractor. In the last of her visits to Malawi, Myra goes to a village where they are using a new method called Deep Bed Farming. It’s more than doubled the yield of some of the farmers and improved their standards of living. The method involves digging deep into the hard earth. This can be tough work but a new solar-powered tractor designed in the UK called Aftrak is helping the farmers. Malawi has been hit hard by the changing climate and often struggles to feed its population. So making it more food secure could improve the lives of millions.
